Join the development of a portfolio of 21 photovoltaic electricity production projects!
OneMW invites you to support the development of 21 photovoltaic power plants spread across several departments in France to produce local, green, and shared electricity.
Designed around an innovative model combining long-term buyers and collective self-consumption, these projects offer security for investors and sustainable support for the host territories.
OneMW aims to raise a first tranche of 500,000 €, as part of a total fundraising goal of 1 million €. The funds raised will be used to finance the development and design studies of the projects. They will also cover the company’s internal expenses, such as employee compensation and other operating costs.
The offer
OneMW is a French company based in Lyon that offers an investment opportunity in the financing of a portfolio of 21 solar power plants located in France, grouped within the company SPV2 ONEMW.
Objective
The crowdfunding operation of the OneMW group aims to raise up to 1 million euros in the form of senior debt in 2 phases of 500,000 €.
Use of Funds
These funds will be used by the project holder to finance external costs related to studies and project design, as well as internal costs such as employee payments and other operating expenses of the company.
Guarantee
Investors benefit from a first-rank pledge on the company holding the project rights.
Tax Exemption Terms
This investment is eligible for the PEA-PME.
Repayment
The repayment of the bonds will take place thanks to the obtaining of senior financing necessary at the construction stage or can also be made by the sale of the projects once the ready-to-build stage is reached.
Specifications
Investment phases
- Investment open to everyone
End of project financing
The closing date for contributions may be extended at the request of the project owner.
The return on your investment will be calculated from the date the subscription certificates are generated, i.e. once all the funds have been received and the legal documentation has been signed by the project owner.

The project
Portfolio of 21 photovoltaic plants under development for a total of 29.3 MWp
The collection aims to finance a portfolio of 21 photovoltaic projects in France at various stages of development.
The cumulative power capacity of the portfolio is 29.3 MWp. The estimated average production to date is 1,313 kWh/kWp/year. OneMW’s strategic positioning is to develop projects with a capacity close to 1 MWp while seizing opportunities to develop larger capacity projects (projects 6, 8, and 20 in the table below).
The portfolio consists of a mix of ground-mounted photovoltaic plants (on low-stakes land) and agrivoltaic-compatible plants (coexistence of agricultural production and photovoltaic activities allowed by the elevation of solar panels above crops). More info on agrivoltaics on our blog Empreinte.
The status column corresponds to the stage of development and obtaining authorizations for the project:
- 09 authorized no appeal: the project has been authorized, there have been no appeals against the project, it therefore enters the pre-construction phase
- 07 K/K obtained: the land is secured, the power plant project is defined and the request for exemption from case-by-case impact studies by the DREAL (Regional Directorate for the Environment, Planning, and Housing) has been obtained
- 06 development: the land is secured and the various studies are underway to design the plant
- 05 securing process underway: the commercial steps have validated the various parameters of the promise of lease on the targeted land. This must be signed in the coming days/weeks.
On the first half of the projects that make up this portfolio, the commissioning will be spread from mid-2026 to the end of 2028 for a total capacity of 16.27 MWp during this period.
Impact
Project owners
OneMW is a French company based in Lyon and Montpellier. Founded in the summer of 2024, it develops ground-mounted solar power plants, on car parks and on rooftops in metropolitan France, with a vision of local energy valorization.
☀️ Small power plants, local loops
The particularity of the company OneMW is to focus its development on photovoltaic power plants with a contained installed capacity. These power plants, with an installed capacity of around 1 MWp, have several qualities:
-
Simplicity and speed of deployment: the development and instruction phases are practically 5 times faster! This acceleration is explained by the exemption from impact studies and simplified urban planning procedures given on a case-by-case basis by the instructing services of the relevant prefectures.
-
Low-stakes land: OneMW focuses on areas with low natural value (wasteland, abandoned areas, areas that have been affected by human activity) and on areas compatible with agrivoltaic projects.
💻 Innovation at heart
In addition to the activities of financing solar power plants, OneMW designs innovative digital solutions. Thanks to the skills and experience of the team, OneMW develops a platform that simplifies and optimizes the development of solar projects and collective self-consumption operations by using the full potential of generative AI tools.
🪜 Strong progress
Created in the summer of 2024, the young company OneMW already supports a remarkable volume of projects:
- 7.3 MWp authorized
- 60 MWp in development
- 30 MWp secured ready to be developed
- 110 MWp in the process of securing land
🤝 Founders & Team
OneMW was founded by 3 partners: Mathieu Le Guennec, Clément Moine and Johann Vanackere. Their company draws its strength from the alliance of their complementary experiences, covering financing to the operation of photovoltaic power plants, but also the creation of complex information systems.
Driven by the desire to contribute to the rise of energy transition rooted in the territories and independent of global markets, they have joined forces to create OneMW.
Their common vision is to build a faster and more inclusive renewable energy model, carried by reasonably sized projects with local energy valorization.
The team has been strengthened by the recruitment of 4 collaborators. Two people focus on project development and the other two conduct prospecting and land securing. By early 2026, OneMW plans to have a workforce of around ten collaborators.
Our analysis
Risk overview
Development risk
Risk relating to authorizations issued to the company and land, and third-party appeals against authorizations issued.
Mitigation methods
Quelques projets sont à un stade de développement avancé. La capacité des autres projets, inférieure à 1 MW, permet au porteur de projet de bénéficier de procédures et de démarches administratives facilitées en comparaison aux projets de plus grande taille. Ainsi, en suivant les décrets en vigueur, les projets de faible puissance développés par OneMW devraient arriver rapidement au stade RTB. La dispense d’une étude d’impact permet par la suite à la société de maintenir la formalité d’une déclaration préalable et non pas d’un permis construire, aux délais plus longs, permit par le Décret n° 2022-1688 du 26 décembre 2022 portant simplification des procédures d'autorisation d'urbanisme relatives aux projets d'ouvrages de production d'électricité à partir de l'énergie solaire installés sur le sol. La société prévoit par la suite le recrutement de nouveaux salariés au cours de l’année, qui devrait donc permettre à OneMW d’accélérer ses process internes et sa capacité de développement de nouveaux projets.
Refinancing risk
Credit risk related to the company's ability to refinance and meet its debt obligations.
Mitigation methods
OneMW possède aujourd’hui près de 40 MWc de projets dans sa pipeline en développement. Ces projets pourront venir se substituer à certains du portefeuille dans le cas d’un ou de plusieurs abandons, permettant ainsi de maintenir un ratio de LTV inférieur à 30%. À ce jour et en moins d’un an, OneMW est parvenu à sécuriser trois projets sur 21. Ses trois projets possèdent leur exonération d’étude d’impact ainsi que leur déclaration préalable. Le portefeuille présente ainsi des projets aux avancements différents, ce qui permettrait au porteur de projet de vendre certains projets pour payer les premiers intérêts Enerfip dans le cas où la partie du financement mis de côté ne serait pas suffisant pour subvenir aux besoins. La sûreté obtenu devrait quant à elle voir sa valeur croître au fur et à mesure de l’avancement du portefeuille.
